Answer 3

#rxxrxxrxxr = r^4#

The short way to write repeated addition is multiplication.

#4+4+4+4+4 = 5xx4 = 20#

Multiplication is a stronger operation than addition.

In a similar way, the short way to write repeated multiplication is using indices or exponents.

#4xx4xx4xx4xx4 = 4^5 = 1024#

Note the difference between

#r+r+r+r = 4xxr = 4r#

And

#rxxrxxrxxr = r^4#

Indices are stronger than multiplication, which is why in an expression with mixed operations, the order is:

powers and roots multiply and divide addition and subtraction

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
